-This invention relatesto improvementsin tape dispensing machine. o

The main object attained in the invention consists in a tape dispensingmachine-adapted in allits parts for cheap productionpneat and compact indesign, and simple and convenient in use. I

Machines for dispensing gummed tape for sealing packages have come intoextensive use. Their economic value as tiine savers, the neatness ofappearance and efiective sealing or binding of packageswhich is madepossible'with their'use, and the convenient and inexpensive meansoiicarrying an advertisement of the establishment ai'iorded by thesections ottape applied to the packages,

gives to machines oi this character me -m tion as a commercialnecessity.

As the devices areused 11 great numbers in establishments Where 1 speedin preparin packages is essential, and neatness an d eti ectivene-ss ofthe packages is required, and

-also'in'small stores where the'fir'st cost 'of the machines" andsubsequent servicecostare determining conditions of their use, theimprovements of the presentinvention areoi? great importance in thefield to which the invention'relates. I *1 1 In the accompanyingdrawings: Fig. 1 is a side elevation of the improved "Figs. 2and 3 areopposite end elevations;

Figs. 4- and 5 are detailviews of the-tape severing mechanism; 1 3 r rFigs. 6,7 and 8 are detail views of the tape advancing mechanisn'i. r IAs shownin Figs.- 1, 2 and 3 the machine as a whole is a compactportable unit adaptcdto set on a counter or table. .Theframe structureconsists of opposite sidem'enibers l, punched from sheet metal andformed to give an artistic' effect to the machineg'the sideinembersbeing oinedf 'one to the other byspacing bones. At the left endof the machine-as viewed inllig. l a curved guide plate-3- and oppositeside guide plates 4 aresuppm't'ed bet-ween the side members 1. At theopposite end. of the machine the side' members 1' are braced betweentheir upper edges by a trans ti-ffen :frame adjacent tape severinganis'm. A longitudinally extended guide 6 is supported betWeensidemembers 1- along their upper edge, the guidebeing provided on 1tsOPPOSItG'SIClQg edges, as best shown incross section in Fig. withinwardly curved open flanges which are adapted to receive the web 14oftapetherebetween as the same is drawn forward from a roll supportedbetween the side members. i 1 1 d The means for drawing the consist of asupporting member 7 arranged to slidetelescopically over the guide member6, as best shown in Fig. 7 and having opposite portions 7* thereof'eXtendedTupwardly to form supports for a pivoted tape engag ng member\COIDPIISXHQ" downwardlyv extended bearingportions 29, a downwardlycurved portion '30 adapted to-engage the tape, an upwardly extendedfinger P1808! 31:,

a rearward and downwardly extended stop 32, a shaft 33 'upon which thepart as a whole is supported anda' spring 34L which acts to hold thepart inoperatively out of engagement with thetape.

'VVhen tape is to be supplied from the machine, pressure is applied totheafinger piece 31 in the forward direction thus causing the tape tobe. gripped between part 30iand the "lower-span of part 71 and at thesame time acting to move the entire. unit longitudinally of guide Gwhichresults'in drawingthe'length of'tape, to which the machine is regulated,from the supply roll, .the length being regulated .by-stop 39. adaptedto 'be set inoneof awseriesaof spaced apertures 40 arrangeda-long theupperedge ot onesot "theside members the stop "being in the path, insideframe 1, ofpart35 and adapted therefore to limit the forward movement ertheft-ape advancing mechanism; mWhen stop "39 is removed the maximumlength oi? tape that can be delivered from the machine will bedetermined by the full movementof part 7 tension spring: l'r'aisconnected to part 35 at one end, anchoredatits .op'posite'endras at18-between side members 1-, the intermediate "portion "of" the springbeing -drawn over a rotatable drum 1 7 as best shown; :in

As the" tap is drawn from the supply roll the same passes over guideplate i -and roller '4 and under] an ecccntrically i mounted pinchroller 8 pivoted on a shaft 9 support ed in'"brackets extended upwardlyfrom "p1ate3,which acts to engage the tape audio IOU prevent retractionthereof in the opposite direction after each dispensing operation.

lit the opposite end ofthe machine, the right end as viewed in big. 1,tape feed rollers 11 and 13 are supported between side members 1, theweb 14' being between the rollers. Roller 11 is supported on a shaft 12and has its lower portion submerged in a water pan 11 and acts thereforeto apply moisture to the gummed sideof the tape. The roller is rotatedby means of a chain 16 traversing sprockets 15, the chainbeing drawnforward by means of a spring pawl 37 pivoted on a stud 36 supported in abracket 35 secured to part 7, a spring 38 acting to cause the pawl toengage a link of the chain when part 7 is moved in the for: warddirection and permitting the pawl to move idly over the chain when part7 is retracted in the opposite direction.

The means for severing the tape consist of pivoted blade 19 having anupwardlyextended finger piece 10 adapted to be engaged at the limit ofthe forward movement of the tape advancing mechanism to actuate theblade for severing the tape. Coacting with blade 19is a cutting blade 5which is secured to bracket 5 and is provided with an upwardly extendedportion 24 to e which blade 19 is pivoted by means of a blade adjustingscrew and nut 21-22. The blade 19 is held in normally raised relation bya spring 25 and is held yieldingly in cutting relation with the cuttingedge of block5 by a spring 27 which is connected at one end to the bladeand is anchored at its opposite end to one of the side members 1.

Operation of the machine, as will be apparent from the foregoingdetailed description, consists in actuating the tape advancing mechanismwith a downward sweep ofthe hand, the hand passing with a shortcontinuous movement in the same direction, upon releasing the tapeadvancing mechanism to the tape severing mechanism, the arrangementbeing thus effective with the minimum movement and in the shortest timeto'deliver a severed length of tape from the machine. As the tape issevered the portion cut oil is drawn from rollers 1113 and applied tothe package, a stripper blade 11 acting to prevent the tape adhering toroller 11.
